What is the element of your quilt that you want to highlight the most? The burgundy pattern? or, the big stitch snowflakes? If you use burgundy for the snowflakes, they will not be snowflakes; but, will balance the overall design. If you use very pale blue or white with a sparkle (metallic) the quilting will become the focus of your quilt. I would encourage you to stitch out a sample to see what you think-you can always make a pillow with your sample.
